Chronology
Predecessor	Mercedes-Benz 4G-Tronic transmission
Successor	Mercedes-Benz 7G-Tronic transmission

5G-Tronic is Mercedes-Benz's trademark name for its five-speed automatic transmission, starting off with the W5A 580 and W5A 330 (Wandler-5-Gang-Automatik bis 580 oder 330 Nm Eingangsdrehmoment; converter-5-gear-automatic with 428 or 243 ft·lb maximum input torque; type 722.6) as core models.

Abstract[edit]

The 5G-Tronic (model W5A 330 and W5A 580 · type 722.6) is an electronically shifted 5-speed overdrive automatic transmission with torque converter lock-up (typically in gears 3, 4 and 5) and 2-speed for reverse. In all applications this transmission is identified as the New Automatic Gearbox Generation One, or NAG1.

It replaced the older 4-speed 4G-Tronic transmission-family and its 5-speed derivative, and was replaced by the much more complex and costly 7-speed^[a] Mercedes-Benz 7G-Tronic (model W7A 700 · type 722.9) transmission with 11 main components,^[b] introduced in 2003. Due to its high torque capacity (up to 1000 Nm) and lower cost, it was still retained for turbocharged V12 engines, four-cylinder applications and commercial vehicles for almost a decade. It is still being built for niche applications (e.g. Sprinter with petrol/CNG M111 engine, Jeep Wrangler, etc.).

Specifications[edit]

Basic concept[edit]

Technical and economic progress is reflected in 5 forward gears^[c] out of 9 main components,^[d] compared to 5 forward gears^[e] out of 11 main components^[f] in the direct predecessor. It is fully electronically controlled and equipped with a torque converter lock-up.

Special operating modes[edit]

Winter/Summer (Standard) Mode[edit]

Activated by a toggle switch, Winter mode sets the gearbox to start off in 2nd gear, both in Drive and Reverse. This is designed to reduce wheelspin on icy surfaces. Also in "W" mode the transmission will shift at lower speeds. "S" mode is not sport but Sommer (German for summer) or Standard.

With Jaguar XJR applications the switch is labelled "Sport". In regular driving mode the gearbox starts off in 2nd gear, both in Drive and Reverse, and will only engage 1st gear when triggered via the kickdown switch (Drive only). While "Sport" mode is enabled the gearbox will always start off in 1st gear.

Speedshift (2001–)[edit]

Speedshift is a performance feature set for the Mercedes-Benz transmissions which includes manual mode and active downshifting. When cornering at high speed, the transmission maintains the same gear above a certain lateral acceleration level. It can also automatically downshift before overtaking.

It was first used in 2001 Mercedes-Benz C 32 AMG^[3] and 2001 Mercedes-Benz SLK 32 AMG.^[4]

AMG Speedshift (2002–)[edit]

A version with mechanical lock-up of the torque converter from first gear and steering-wheel-mounted shifter. AMG Speedshift is also used in 7G-Tronic transmission.^[5]

It was first used in 2002 Mercedes-Benz E 55 AMG, S 55 AMG, C55, CL 55 AMG.^[6]

AMG Speedshift R[edit]

A version used in Mercedes-Benz SLR McLaren. It includes three manual modes.
